‘71 340 Rebuilt Shortblock
Selling a cast-in-1970 340 shortblock. Casting date is 6/29/70
Stamping on the driver’s front head flange: GW340P33640033
VIN stamp is 1B184616
Also factory stamped with Maltese cross and “X” so it was a factory .010/.010 crank and bearing assembly.
Has been cleaned, magged, sonic tested, bored, honed .060 over, and decked. Crank turned to .020/.020. Rods resized w/ARP bolts and new pin bushings. Assembly balanced.
I bought it fully machined, and I did the sonic test. Machining quality is good. I assembled it and it comes with the assembly sheet, sonic test, and balancing paperwork. Cam bearings are installed but not clearanced. All new block hardware and brass core plugs. Pistons are .020” proud of the deck.
Pistons are KB243-060. Ring set is also KB and they are gapped properly for these pistons and heavy use but no boost or NO2. Durabond cam bearings. Cleavite rod and main bearings.
Comes with factory windage tray, oil pan, cam retaining plate, and oil slinger. Would make a nice mild engine. Willing to discuss finishing the engine for the buyer for additional money. Located in Columbia CT 06237 and no I won’t ship but will deliver or meet up to 250 miles from my zip code for additional fee. Asking $2999.00 or make an offer.
